(gzipped) PostScript## Magnetic fields and large scale structure in a hot universe## I. General equations
Departamento de Física Teórica y del Cosmos, Universidad de Granada, E-18071 Granada, Spain
We consider that no mean magnetic field exists during this epoch, but
that there is a mean magnetic energy associated with large-scale magnetic
inhomogeneities. We study the evolution of these inhomogeneities and their
influence on the large scale density structure, by introducing linear
perturbations in Maxwell equations, the conservation of momentum-energy equation,
and in Einstein field equations. The primordial magnetic field structure is
time independent in the linear approximation, only being diluted by the general expansion, so that
